A man asked the Prophet about the Hour (i.e. Day of Judgment) saying, "When will the Hour be?" The Prophet said, "What have you prepared for it?" The man said, "Nothing, except that I love Allah and His Apostle." The Prophet said, "You will be with those whom you love." We had never been so glad as we were on hearing that saying of the Prophet (i.e., "You will be with those whom you love.") Therefore, I love the Prophet, Abu Bakr and 'Umar, and I hope that I will be with them beCause of my love for them though my deeds are not similar to theirs.

(Narrated by Anas - al-Buhkhari 5.37) [src: alim.org]

"The Messenger of Allah  (صلى الله عليه وآله وسلم) said:‘Verily Allah the Almighty has prescribed the obligatory deeds, so do not neglect them; He has set certain limits, so do not go beyond them; He has forbidden certain things, so do not indulge in them; and He has said nothing about certain things, as an act of mercy to you, not out of forgetfulness, so do not go enquiring into these.‘"

[It was narrated on the authority of Abi Tha'labah Al-Khushani Jurthum bin Nashir, radiyallahu 'anhu - Related by Al-Daraqutni and others - Al-Nawawi said this is a hasan (fine) hadith]

" إِنَّ اللهَ تَعَالَى فَرَضَ فَرَائِضَ فَلاَ تُضَيِّعُوهَا، وَحَدَّ حُدُوداً فَلاَ تَعْتَدُوهَا، وَحَرَّمَ أَشْيَاءَ فَلاَ تَنْتَهِكُوهَا، وَسَكَتَ عَنْ أَشْيَاءَ رَحْمَةً لَكُمْ غَيْرَ نِسْيَانٍ فَلاَ تَبْحَثُوا عَنْهَا"
[حَدِيثٌ حَسَنٌ رَوَاهُ الدَّارَقُطْنِي وَغَيْرُهُ]
